Despite decades of research, no efficacious chemotherapy exists for the treatment of prostate cancer. Malignant prostate zinc levels are markedly decreased in all cases of prostate cancer compared to normal/benign prostate. ZIP1 zinc transporter down regulation decreases zinc to prevent its cytotoxic effects. Thus, prostate cancer is a "ZIP1-deficient" malignancy. A zinc ionophore (e.g. Clioquinol) treatment to increase malignant zinc levels is a plausible treatment of prostate cancer. However, skepticism within the clinical/biomedical research community impedes significant progress leading to such a zinc treatment. This report reviews the clinical and experimental background, and presents new experimental data showing Clioquinol suppression of prostate malignancy; which provides strong support for a zinc ionophore treatment for prostate cancer. Evaluation of often-raised opposing issues is presented. These considerations lead to the conclusion that the compelling evidence dictates that a zinc-treatment approach for prostate cancer should be pursued with additional research leading to clinical trials.

Disseminated intravascular coagulation (DIC) is a hematological disorder characterized by the abnormal activation of the coagulation system, which leads to widespread clotting and subsequent consumption coagulopathy. DIC is often associated with the progression of prostate cancer and can be a life-threatening condition. In this case report, we present a patient with recurrent DIC in the setting of advanced prostate cancer.

Individuals with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have a high risk of developing other malignancies (OMs). The development of OMs may be associated with the advanced age of CLL/SLL patients, presence of a tumor-promoting microenvironment, immune alterations inherent to CLL/SLL, or chemotherapy. Importantly, the occurrence of OMs following frontline fludarabine, cyclophosphamide and rituximab (FCR) treatment is associated with a reduction in the overall survival (OS).

However, high-resolution insights into how cell phenotypes evolve across successive stages of PC remain limited. Here, we present the Prostate Cancer Cell Atlas (PCCAT) by integrating ∼710,000 single cells from 197 human samples covering a spectrum of tumor stages.

Here, we integrated single-cell RNA sequencing, single-cell multiomics, and spatial transcriptomics to define the transcriptional, epigenetic, and spatial basis of cell identity and castration response in the mouse prostate. Leveraging these data along with a meta-analysis of human prostates and prostate cancer, we identified cellular orthologs and key determinants of ADT response and resistance.

Primary small cell neuroendocrine carcinoma of the prostate is extremely rare, highly aggressive, and has a very poor prognosis, with an overall survival typically not exceeding one year. Standard treatment is generally based on the regimen for small cell lung cancer (SCLC), with guidelines recommending etoposide combined with cisplatin (EP regimen) as the first-line treatment. However, their therapeutic effects are limited.
